Application filed November a7; ma, Seria1 No.733,8 67.

To-all whom it may concern Be it known that I, FERDINA I a citizen-ofthe United States, residing at descent lamps.

Saginaw, in the county of Saginaw and State of Michigan, have" inventedcertain:

new and useful Improvements in Lam Structures, of which the following isa specification. i l

This invention relatesto improvements in lamps, and more particularly toreflector and shade attachments for inverted incan- The object in viewis the pro'ecti'on of a maximum number of light rays ownwa'rd-l from theoint of illumination, and wit this object 'in view the inventioncomprehends the disposition of a shade and a cooperating reflectordisposed for supplementing the reflection afforded by the shade with outinterfering with air circulation. The invention further includes thedisposition of a reflector sustained upon the burner supporting tube anda shade suspended therefrom in appropriate relative position with,respect to the light disposed at theterminusof the supporting tube.

' The inventlon also comprises certain other novel constructions,combinations and ar-' rangelnents of parts,=as will be hereinafterspecified and claimed.

n the accompanying drawing Figure 1 is'a view partly. in elevation andpartly in section of a light structure'embodying the.

features of the present. invention. Fig. 2 is a transverse section takenon the plane indicated by line 2'2 of Rig. 1 and lookingdownwardly,parts being broken away. Fig.

3 is an enlarged detail verticalsection taken approximately on the lineindicated by line 3'3 of Fig. 2. Fig. 4 is an enlarged detail verticalsection of a fragment of the parts adjacent the point of supportingengagement with "the supporting or supply pipe. Fig. 5- is a.longitudinal, vertical, central section through the mantle support, afragment of .the mantle being shown and the also constitutes parts beingshown .on an lenlargedscale. ig. 6 is a top plan view of. the mantlesupport.

Referring to the drawing by numerals, .1 indicates a gas su ply pipe ortube which the supporting tube and i which is supplied with gas througha mixer NnPmszmr;

2.- To the lower end of the pipe 1 is connected the incandescent mantlesupport 3 provided with a mantle 4. Tube 1 is provided with an annularhead 5 spaced above fthe'. connection or support 3. 'The bead 5 may;obviously-either be formed integral with the supply pipe I or be formedb a to the pipe in any separate ring attached sultable manner. a v

'The mantle support 3, as clearly indicated in Fi 5 and 6, consistsessentially of a tube ormed preferably with integral out standing arms 3supporting a surrounding ring 3"; whichring is formed with an annulargroove 3 into which is secured the upper end of the mantle 4,said mantlebeing confined in the groove by a retaining ring 3 which may be a cord,tied or otherwise fastened in position, and if a cord it is formed, ofcourse, of the same material as the mantle. The ring 3" is preferablyformed integral with the arms 3.

Surrounding the head 5 is a ring (3 having an inwardly turned annularflange 6 dis.- d aboveand adapted to rest upon the end 5- Outstandingradially and preferably inclined slightly downwardly from and preferablyformed integral with the ring 6 "are supporting arms .7, 7 eachterminating at its ower outer end in a hook 8 disposed to underlie theinclined outer surface of an inverted frusto-conical ring 9. The loweredge of the ring 9 is preferably stiffened by being thickened andprovided at suitable intervals with set screws 10 adapted to engage theupwardly flared end of a mantle globe ll inclosing the mantle 4. Theglobe 11 may be of any ordinary type and is preferably provided with aircirculation apertures 12, 12.

Disposed above the ring 6 is a reflector 13.

tor l3 terminates in an upstanding flange it having tabs 1;) strucktherefrom at various points about the fla iige. A spider 16 is arrangedwith an opening having an annular boss 17 disposed to fit about the pipe1, with the arms of the spider extending radially from the pipe to theflange 14, there being an arm of the spider for each tab 15, therespective arm of the spider extending beneath the respective tab 15 inposition for resting upon the inclined outer portion of the reflector18. Thus the reflector 13 is comparatively rigidly sustained on the pipe1 in proper relative position with respect to the burner and globebeneath.

Hooks 18 are spaced about the reflector 13 and are preferably providedin a number upper hook portion of each hook 18 engaging the flange 14adjacent one of the tabs 15, the shank of each hook 18 being pendentfrom the flange and at its l'ower end being provided with a pairof-spaced hooks 18 adapted to engage suitably disposed-apertures in aring 19. The ring 19 converges downwardly in a ratio proportionate tothe upward flare of the upper end portion 20 of a shade 21, the saidflared portion 20 being surrounded and clamped by the ring 19.

The said ring 19 preferably consists of a strip of metal or othersuitable material having its end portions bent and detachably securedtogether as oy bolts or other securing means 19, 19. The shade 21 isformed of suitable mate ial with preferably an ap propriate reflectinginner surface and shaped and dimensioned relative to the size anddisposition of the light in the lobe 11 for effectively projecting thelight rays downwardly, supplemented by theprojection of light raysreflected from the under surface of the reflector 13.

Having thus described the invention,what is claimed as new is: i
